The nucleus of an atom has 5 protons and 6 neutrons. What will be the noumber of valence electrons?
DO THE BEST AND HOPE FOR THE BEST!!
RESULT IS NOT IN YOUR HANDS!!!

HAVE A NICE DAY!!!

 protons= electrons=5,which is the atomic number.
 
so no.of valence electrons : 3 !

Atomic number = number of protons = 5
Hence the electronic configuration is 1s2 2s2 2p1  .
Number of valence e- = 3.

NO OF PROTONS ==NO OF ELECTRONS
THEN WRITE ELECTRONIC CONFIGURATION AND U WILL GET 3 VALENCE ELECTRONS
